So sorry to hear about your leakage. I had gastric bypass and had a leak early on. I know how scary that can be. I had the same thoughts about my leak about how do I know it's healing and not leaking again? All I can say is take everything slow with your recovery and that if you feel something is wrong call the doctor. My leak fortunately healed on its own. It took 16 extra days in the hospital, tons of antibiotics, a drainage tube, countless cat scans and X-rays, and TPN through a picc line with nothing by mouth for 14 days. Thanks to my entire surgical team and nursing staff (at a military hospital) who took the best care of me! I am now 9 months post op and feeling great. I hope everything with your recovery goes great! Do exactly what your surgeons say and don't push yourself!
